vlight command has been revised to provide more friendly syntax. Command now accepts light index or name as first argument. Added arguments -enable/-disable for managing enabled state. Added argument -reset to reset light parameters to default values. V3d_Viewer::SetDefaultLights() now sets names "headlight" and "ambient" to created lights. Graphic3d_TypeOfLightSource enumeration values have been renamed to avoid shortcuts. Draw::Atof(), applied corrections to avoid explicit new/delete calls.
